Title: Preparation of acetic acid ester
Inventor: GOTOU YUKIHISA
IPC: B01J31/00
Filed: 1979-06-01
Abstract: PURPOSE: To prepare an acetic acid ester, in extremely high conversion and selectivity, economically in an industrial scale, by adding an olefin to acetic acid in aqueous phase using trifluoromethanesulfonic acid as a catalyst.  
     CONSTITUTION: Addition of a ≤5C olefin, e.g. ethylene, propylene, 1-butene, etc., to acetic acid in aqueous phase in the presence of trifluoromethanesulfonic acid as a catalyst gives the corresponding acetic acid ester in extremely high conversion and selectivity. The amount of trifluoromethanesulfonic acid is generally 0.05W10wt% based on the amount of acetic acid used as the starting material. Said catalyst can accelerate the reaction rate compared with mineral acids, e.g. H 2 SO 4 , or similar organic sulfonic acids. Moreover the catalyst scarcely causes side reactions, e.g. polymerization of olefin, causes no corrosion of the apparatuses, and has an excellent stability and a long lasting activity. Therefore its catalytic properties are excellent for industrial use.

Abstract: PURPOSE:To improve the operability by setting a character font mode having the highest operating frequency as a default value and converting it automatically after the execution of input by other character font mode to decrease the number of times of operation of character font mode conversion. CONSTITUTION:While an initializing key on a keyboard 1 is depressed in the setting of the initializiag mode, a character font mode designation key having the highest using frequency is depressed. Thus, a default value of the depressed mode is set to a mode set section 2 as the initial mode in this way. When the switch of the initial mode is turned on at the same time so as to initialize the mode. In conducting Kana (Japanese syllabary)-Kanji (Chinese characters), the character font mode is processed other than the set character font mode and when an execution key is inputted at the end of the former processing, the character font mode is converted automatically into the initial mode. Thus, the mode is converted automatically to the initialized mode without any key operation of the operator, the number of times of operation of character font mode conversion, allowing to improve the operability.

IPC: H01B1/12
Filed: 1987-03-24
Abstract: PURPOSE:To obtain a modulatable molecular element having a high function, which can execute weighting to input information, by giving a variation to a coupling state of a constitution object by the stimulus energy from the outside, such as light, electric field, heat, pressure, etc. CONSTITUTION:A molecular aggregate consisting of a combination of AB1, AB2-B4A exists, and B executes an interaction with A in a state shown by a lozenge and in this case, it is in an insulating state. On the other hand, when a prescribed stimulus energy m1 has been applied from the outside, several Bs are displaced, for instance, as B2 and B4, and execute an interaction strongly with A. However, undisplaced B1 and B3 remain as they are as a whole, there fore, they are still in an insulating state. When that which exceeds a stimulus m2 is further applied, the remaining B1 and B3 are also displaced, and all Bs execute an interaction strongly with A, and the whole changes to conductivity. Also, when the external stimulus is eliminated, the whole returns to its original stable state. As for a material for executing such as interaction, polyacetylene, chelate compound, chalcogenide, etc., are preferable.

Abstract: PURPOSE:To realize an optical switch which allows easy and exact optical axis alignment by using a specific flexuous displacement piezoelectric actuator. CONSTITUTION:This optical switch is disposed with two pieces of output side optical fibers 2-1, 2-2 and one piece of an input side optical fiber 1 to face each other and changes over optical paths by moving the light from the input side optical fiber 1.

The input side optical fiber 1 is changed over from the output side optical fiber 2-1 to 2-2 to which the input side optical fiber is opposed by the flexuous displacement of the actuator 10 when a DC voltage is instantaneously impressed from a voltage source 9 to the piezoelectric actuator 10. The piezoelectric actuator 10 returns to its home position and the input side optical fiber 1 faces again the output side optical fiber 2-1 when the DC voltage is removed. The changing over without hysteresis is executed in this way.

Abstract: PURPOSE:To suppress the occurrence of a delay time distortion, by installing two adjustable phase shifters so that the phase of an unnecessary signal wave caused by turnabout between the two antennas is equal or opposite to the phase of a received signal. CONSTITUTION:The phase shifters PS1 and PS2 provided at the output parts of amplifiers AMP1 and AMP2 are controlled so that the phase of an unnecessary signal wave caused by turnabout between antennas ANT1 and ANT2 is equal or opposite to the phase of a received signal. As a result, the using frequency band is within a range shown by BW1 or BW3 and within a band width of about 5MHz for the signal of a microwave band to be used for a multiplex telephone circuit to ensure an optimum application. When the phase has a variation of 90 deg., the distortion becomes maximum at the position of BW2. On the other hand, the inserting positions of the shifters PS1 and PS2 can be identical with the input parts of the amplifiers AMP1 and AMP2, respectively. In such case, the insertion part can be decided by taking the signal loss of the phase shifter into consideration.
